Historical loss of groundwater-dependent terrestrial ecosystems in undrained and artificial drained landscapes in Denmark

Autor: Gasper L. Sechu, Bertel Nilsson, Bo V. Iversen, Mette B. Greve, Mogens H. Greve

Groundwater-dependent terrestrial ecosystems (GWDTE) have been increasingly under threat due to groundwater depletion globally. Within the past 200 years, there has been severe artificial drainage of low-lying areas in Denmark, leading to a gradual l

River valley bottoms have hydrological, geomorphological, and ecological importance and are buffers for protecting the river from upland nutrient loading coming from agriculture and other sources. They are relatively flat, low-lying areas of the terr
